So my front assembly has enough wobble to throw off my shots when i move around. Ive went through the gun and im goin nuts trying to find out what to screw in. Ive tightened those small hex screws on both side of the outer barrel near the delta ring and the one hex screw on the the top rail, but nothing works. Anyone have any idea where the screw im supposed to tight is?

Please elaborate more on what you mean by front assembly. Is it the entire front of the gun past the reciever, just the sight post/sight, the entire barrel still wobbles?

Have you tried tightening the entire barrel locking collar where the barrel meets the reciever? The ring at the start of the foregrips that slides back so you can remove the grips, that whole assembly is threaded and has a collar on the inside, when you tighten the assembly the collar will pull the barrel base(the piece which has the 4 set scews) back and tightly into the receiver, if its loose most of the front will wobble, including the gas tube, grips, barrel and anything attached to it.

Which model do you have? When you said front assembly, do only mean the barrel or the whole front set?
Our barrel is secured with 4 set screws on the base (2 on each side) so there is a possible up and down movement. However, the standard hand guard assembly will lock down the barrel with the ring behind the front sight.

The delta ring is separate from the collar at the back of the gun, the delta ring is the triangular "ring" that holds the front of the grips together and centered over the barrel. The Barrel locking ring assembly at the back has a spring loaded collar, now you'll also notice that once you take off the grips the base of the ring assembly looks like a spur, with rather sharp "teeth" all the way around it, that is attached to the rest of the ring assembly base which threads onto the receiver and holds the barrel base onto the receiver as well. Take a rag and spread it over your hand, use something rather coarse but not too thick, like a dish rag, pull the collar back as far as you can with one hand, then grip the spurs and rotate the assembly to see if you can tighten it, you will rotate it clock wise to tighten if you are facing the front of the gun(as in looking down the barrel). You may only be able to tighten it a little bit, and it shouldn't be too loose because if the Gas tube is still in there it will only allow the collar to rotate a few degrees, but it may be enough to cause wobble. Also if you think the barrel base may be cracked or broken, remove the gas tube, then you can unscrew the collar and remove the outer barrel and inspect it. Make sure to remove the inner barrel and hop up first if you remove the outer, as it will help avoid accidentally damaging them as they are not meant to take that kind of stress.

If you want to test it before you try that, take off the grips only and try moving/wiggling the barrel, you should be able to see where its loose, pay close attention to the barrel base with the 4 set screws, see if the base itself is moving inside the receiver.

I have a KM4A1 and when i mean the front assembly i mean the ENTIRE front assembly not just the barrel but the handguard too. And i dont think the barrel screws are the problem I think it has to do something with the retaining collar or the base of that

I call it the barrel nut as well. Yes... you'll need armorer wrench to tighten it.

A simple dish rage and strong hand will do just fine ;-). Its a trick my army buddy who just got back from Iraq suggested if you don't have an armor's tool on the real AR's. Works just as well for airsoft. It may not work if the "barrel nut" is thread locked on, then you'll probably need the tool, but I don't think KWA thread locks theirs.
